<p>I know there are some requirements when it comes to code that requires changes in both libraries and the compiler. Part of the diagnostic changes I'm implementing requires a change in <code>compiler/rust_macros/src/session_diagnostics.rs</code>. However, this appears to be using the nightly compiler that I have installed, even when called via <code>x.py</code>. What's the proper way to go about making the necessary change?</p>

<p>you can also use <code>x.py build library/std</code> which defaults to <code>--stage 1</code>, but that might be more confusing than helpful at this point <span aria-label="laughing" class="emoji emoji-1f606" role="img" title="laughing">:laughing:</span></p>

<p>To be clear, what I was <em>hoping</em> would happen is an error message that implied it was being built with my local changes. A successful build should not happen, as there is local code referenced that no longer exists.</p>
